+"""Tests for IPython's test support utilities.
+
+These are decorators that allow standalone functions and docstrings to be seen
+as tests by unittest, replicating some of nose's functionality.  Additionally,
+IPython-syntax docstrings can be auto-converted to '>>>' so that ipython
+sessions can be copy-pasted as tests.
+
+This file can be run as a script, and it will call unittest.main().  We must
+check that it works with unittest as well as with nose...
+
+
+Notes:
+
+- Using nosetests --with-doctest --doctest-tests testfile.py
+  will find docstrings as tests wherever they are, even in methods.  But
+  if we use ipython syntax in the docstrings, they must be decorated with
+  @ipdocstring.  This is OK for test-only code, but not for user-facing
+  docstrings where we want to keep the ipython syntax.
+
+- Using nosetests --with-doctest file.py
+  also finds doctests if the file name doesn't have 'test' in it, because it is
+  treated like a normal module.  But if nose treats the file like a test file,
+  then for normal classes to be doctested the extra --doctest-tests is
+  necessary.
+
+- running this script with python (it has a __main__ section at the end) misses
+  one docstring test, the one embedded in the Foo object method.  Since our
+  approach relies on using decorators that create standalone TestCase
+  instances, it can only be used for functions, not for methods of objects.
